Pros: The product and perks are great, offering free lunch and snacks along with good insurance.

Cons: I didn’t find anything to add here.

Pros: I've been in Silicon Valley startups for close to thirty years. Illumio is a very special place. The company is well over 300 people, but the engineering culture has remained open, and collaborative. From my experience, the senior engineering staff are approachable and friendly. I can (and do) stop people and ask them about details of their design at any point. Engineering ideas are evaluated, by and large, based on merit (and best practices). There is plenty of innovation that happens every day at Illumio. I enjoy coming to work, contributing to a great product, and working with a good team. Is the company perfect in every way? It is not. However, it is still one of the best places I have worked. The company is successful both technically, and commercially.

Cons: Illumio cannot be run like a small startup anymore (mostly due to our success). There are growing pains associated with this shift in company strategy. Some new leadership has been brought in to help take Illumio to the next level. They have restructured their organization as they saw fit. From a personal perspective it's hard to see people you've worked with for years leave the company (for any reason). However, this happens at every company, regardless of size or success.

Pros: The factors were a learning opportunity, leadership, people, culture, and work-life balance.

Cons: None for me and everything is great.
